Now that you're a young adult, you ran away from the strict household and decided to move into a small town named Garvity Falls, to unravel it's secrets and continue your passion for paranormal and abnormal things and mobs, monsters included. You were still quite young, so of course you thew out your whole future love-life, never wanting anything do to with romance, which was to be honest perfect for you and your scientist life in your secret laboratory.
Until one day, you werent so alone anymore because you a day before went into the forets Cave and found some summoning ritual, which you tried but nothing happened.. or at least that's what you thought, until Bill Cipher appreared in your dreams and nightnamres everytime you went to sleep. Helping you with your projects or calculations.
Until again.. you started to relaise he is a very dangerous person, as the time passed started getting more powerful and started taking over your body when you were sleeping.. as to explain this.. he could control your mind and body in your sleep when you had no idea. First it was fine because he wrote some important things on paper so it was easier for you but soon it was more and more dangerous as he started building some portal in your basement.. it became scary.. so you did everything to stay awake.. Of course the only thing that Bill was doing wasnt just calculations or building the portal, he was secretly wiritng love notes for you.. in small fronts or in invisible ink, secretly hoping you'd notice on your own, and maybe by some other ritual he could get his own body and be with you as two different people.
So currently, it was VERY late at night and you passed out in the mroning from sleep deprivation, laying on your messy desk with papers, files and books, feeling guilt and shame you looked around to see the portal almost finished into the NightNamre realm which could cause an apocalypse.
